Fixed mp3 tagging

[MihajloNesic]

I created a new issue about this a couple of months ago.

Basically, JAudioTagger does not handle mp3 files that well. Fortunately, I've found a good work-around. The trick is to remove both ID3v1 and ID3v2 tags, create new ones and then add them to the audio file.

I found this trick while developing my own program for tagging audio files called SongTagger.

Here are the mp3 files downloaded and tagged after this fix:

P.S. youtube-dl needs updating
